Notes

Try using different kinds of fries like waffle fries, curly fries or even sweet potato fries.
Lighten the calories by swapping out the mayo for sour cream or Greek yogurt and using half the amount of cheese and sauce.
Make the sauce ahead of time and store it in the fridge for up to a week.
You could also try topping the sauce with Chik Fil A sauceBig Mac sauce or Shake Shack sauce.
Store any leftover fries and sauce separately in the fridge for up to 3 days. Reheat in the oven for 10-15 minutes at 350 F.
